Abstract

L'invention concerne un clapet antiretour, notamment à usage médical, comprenant un premier boîtier de raccordement de flexible et un second boîtier de raccordement de flexible, ainsi qu'un disque membranaire disposé entre les deux boîtiers de raccordement de flexible et consistant en un matériau flexible, qui peut être soulevé, en cas de surpression dans un passage d'accès, dans le premier boîtier de raccordement de flexible, par un siège de soupape annulaire, entourant l'espace d'entrée relié au passage d'accès et qui, en cas de surpression dans un passage de sortie, peut être comprimé de manière fiable et dans des temps minimaux, sur le siège de soupape. Le disque membranaire comporte au niveau de sa zone périphérique extérieure, un bourrelet annulaire qui est logé dans des rainures annulaires opposées des boîtiers de raccordement de flexible. Le disque membranaire est muni d'ouvertures, dans le sens radial en dehors du siège de soupape, lesdites ouvertures étant reliées à un espace de sortie. Sur la paroi (26) opposée au disque membranaire (6), du second boîtier de raccordement de flexible (4), il est prévu une formation (28) située sur la face du disque membranaire (6) tournée vers l'espace de sortie (22). Ladite formation maintient ou contraint le disque membranaire (6) en direction de l'espace d'entrée (10). Ladite formation (28) est disposée à l'intérieur de la limite définie par le siège de soupape (12).
